Here is what Razoola posted at the time of release of the MVS/AES release:
"Audio changes.
Taken music from Crossed Swords 1 as no complete music (with samples) available.
New Attract mode background music.
New background music for title page after inserting a coin.
New background music on all game play levels.
New background music for battle mode bonus count screens.
Stopped background music on bonus counts and before shop for smoother transitions.
Slightly delayed shop music start to make overall game flow better.
Adjusted attract mode character graphic timing slightly to match attract mode music better.
Shortened attract mode title page dislay time to account for shorter music.
Synced 'game over' graphic timing to match the new game over jingle.
Removed static popping mostly after FM sounds stop playing.
Removed static popping sounds in some back ground music (noticable in tune 0x14 and 0x1F).
Track 0x0C now uses a different sample to make it sound better."

The rom I have for the MVS/AES conversion doesn't work on my RetroArch HEXAeco FB Alpha Neo VM core though. Does it work on Wii?
Also, I didn't know that it was converted by Razoola, the creator of the Universe BIOS.
